With a 12th championship title already in the bag, Hakuho exacted swift revenge over Asashoryu on Sunday to wrap up the Kyushu Grand Sumo Tournament with a perfect 15-0 record.
Seeking to snap a three-bout losing streak, Asashoryu gave as good as he got in an epic battle at Fukuoka Kokusai Center, but Hakuho stood his ground and secured yokozuna bragging rights with a textbook overarm throw.
Hakuho, who clinched the title with victory over Kotomitsuki on Saturday, has won a single-year record 86 victories against four losses in 2009.
